Code:
#include <iostream>

using namespace std;

int main()
{cout<< "Welcome to RollCast's Classic Salmon Fly Proportion Calculator!"<<endl;
int gape;
cin>> gape;
cout<< "Your hook gape ="; cout<< (gape); cout<< "mm"<<endl;
cout<< "Please select which tyers proportions you wish to use"<<endl;
cout<< "1: Kelson \n2: Cohen \n3: Alcott \n4: Carne \n5: Guidry \n6: Inman \n7: Boyer \n8: Ostoj \n9: Gotzmer"<<endl;
cout<< "Please input the number for which proportion you wish to use"<<endl;
int tyer;
cin>> tyer;
float dtl;
float has;
float dbb;
switch (tyer)
{case 1:
dtl =1.8;
has =0.8;
dbb =0.7;
break;
case 2:
dtl =2;
has =0.875;
dbb =0.5;
break;
case 3:
dtl =1.4;
has =0.7;
dbb =0.3;
break;
case 4:
dtl =1.8;
has =1;
dbb =0.44;
break;
case 5:
dtl =1.88;
has =1.1;
dbb =0.75;
break;
case 6:
dtl =1.9;
has =0.81;
dbb =0.69;
break;
case 7:
dtl =1.78;
has =0.5;
dbb =0.83;
break;
case 8:
dtl =2;
has =0.78;
dbb =0.78;
break;
case 9:
dtl =1.69;
has =0.58;
dbb =0.53;
break;
default:
cout << "Not a valid option" << endl;
}
cout<< "Diagonal tail length ="; cout<< gape*dtl; cout<< "mm"<<endl;
cout<< "Height above shank ="; cout<< gape*has; cout<< "mm"<<endl;
cout<< "Distance behind bend ="; cout<< gape*dbb; cout<< "mm"<<endl;

cout<< "Thanks for testing, RollCast \n Press ANY KEY to continue";

return 0;
}
When I try to debug this it stops the console window at the part:

Code:
...
float dtl;
float has;
float dbb;
switch (tyer)
{case 1:
dtl =1.8;
has =0.8;
dbb =0.7;
break;
...
but doesn't give me any error messages?

I just ran this code and my debugger didn't crash. By the looks of it, it seems good. What exactly is the problem?

When I try to save the code as a .exe so I can email it to some people who wanted it, the console opens when the .exe is ran but then stops and closes at the part I indicated.

My bet is that it displays the message and then closes the console - as there is no reason for the console to stay open. Console closes so fast, it is impossible to see that the message was displayed.

Think what my problem is that the person I'm trying to send it to hasn't got a compiler for c++, is there any way I can save it so he doesn't need to install a compiler?

Sorry I just realised that I had forgotten to code a pause into the end of it

... or you could tell the person to run the program from a dos console window. For windows XP, you'd click on programs / accessories / command prompt. I assume that the "pause" function asks the user to press the enter key to continue?
